Vibrio vulnificus is a leading cause of seafood-related deaths in the United States. Sequence variations in the virulence-correlated gene (vcg) have been used to distinguish between clinical and environmental V. vulnificus strains, with a strong association between clinical ones and the C sequence variant (vcgC). In this study, vcgC was selected as the target to design a loop-mediated isotherma...

A pure bacterial strain capable of aerobic biodegradation of fluorobenzene (FB) as the sole carbon and energy source was isolated by selective enrichment from sediments collected from a polluted site. 16S rRNA and fatty acid analyses support that strain F11 belongs to a novel genus within the alpha-2 subgroup of the Proteobacteria, possibly within a new clade related to the order Rhizobiales. I...

background and objective: probiotics are live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance, producing metabolites which inhibit the colonization or growth of other microorganisms or by competing with them for resources such as nutrients or space. the aim of this study was to investigate the probiotic properties of candida fam...

two organisms with bacteriophage active against the bacterial contaminant. We undertook to carry out the latter procedure. The contaminating bacteria were isolated by plating on agar and identifiedv as belonging to the salmonella group. They fermented glucose, mannite, maltose, arabinose and dulcite with the production of acid and gas; lactose, saccharose, and salicin were not affected. Litmus ...

mRNA differential display has been used to identify cyclohexanone oxidation genes in a mixed microbial community derived from a wastewater bioreactor. Thirteen DNA fragments randomly amplified from the total RNA of an enrichment subculture exposed to cyclohexanone corresponded to genes predicted to be involved in the degradation of cyclohexanone. Nine of these DNA fragments are part of genes en...

Pseudomonas pseudoalcaligenes POB310(pPOB) and Pseudomonas sp. strains B13-D5(pD30.9) and B13-ST1(pPOB) were introduced into soil microcosms containing 3-phenoxybenzoic acid (3-POB) in order to evaluate and compare bacterial survival, degradation of 3-POB, and transfer of plasmids to a recipient bacterium. Strain POB310 was isolated for its ability to use 3-POB as a growth substrate; degradatio...

In this study, Limosilactobacillus fermentum PTCC 1638 and Lacticaseibacillus rhamnosus 1637 were used alone in combination to ferment quinoa seeds, the effect of fermentation (37 °C; 24 h) on pH, total phenols, tocopherols, vitamin C, antioxidant activity, enzymes inhibition (α-amylase α-glucosidase; antidiabetic effect) was investigated. The results showed that with increase time, bacterial p...

The antibiotic potentiating activity against standard and multidrug-resistant Escherichia coli Staphylococcus aureus bacterial strains of the natural compound 5”-O-α-L-raminopyranosyl-1’-β-D-glycopyranosyl-4’,6-dimethoxyflavone (pectolinarin) isolated from L. camara leaves was evaluated. Tests for antibacterial pure substance analysis potentiation pectolinarin associated with antibiotics were c...

phenol and phenolic compounds are among the most recognized environmental pollutants which exist in industrial wastewater and enter the biological cycles due to the solubility in water. Bioremediation is one of the cost-effective and Eco-friendly methods for phenol removal. In this study, the most effective phenol-degrading bacterial strain was isolated and identified from the shores of the Oma...
